Probing nonlinear structure formation beyond CDM with the LSS bootstrap: a joint power spectrum and bispectrum analysis
Giorgia Biselli, Marco Marinucci, Guido D'Amico +1
We present the first MCMC-derived constraints on the parameters of the Large Scale Structure (LSS) bootstrap, a model-independent framework that captures deviations from CDM us…

Euclid preparation. Galaxy power spectrum modelling in redshift space
Euclid Collaboration, B. Camacho Quevedo, M. Crocce +292
Accurate modelling of redshift-space distortions (RSD) is essential for maximizing the cosmological information extracted from large galaxy redshift surveys. In preparation for the…

The cosmological analysis of DES 32pt data from the Effective Field Theory of Large-Scale Structure
Guido D'Amico, Alexandre Refregier, Leonardo Senatore +1
We analyze the Dark Energy Survey (DES) Year 3 data using predictions from the Effective Field Theory of Large-Scale Structure (EFTofLSS). Specifically, we fit three two-point obse…
